Good evening everyone,

I am very very new to Perl.

My challenge is: Two similar datasets (thousands of rows & 3 columns in each of them): 

T2 23 43 
T2 45 78 
Tn 66 124 

T2 34 lit
T3 20 mir
Tn 100 net2
Tk 1234 low3

I want to: Find #2dataset elements that are in #1dataset range.

How the workflow should go (in my opinion):Element (LetterNumber or LetterLetter) from the first column of #2dataset matches Element from the first column of #1dataset => Element's Number from the second column of #2dataset is compared to equivalent Element's Ranges (second & third column) of #1dataset => If Number (#2dataset second column) is in any Range => Code from the third column of #2dataset is printed

What I was able to create by myself: 

 
#!/usr/bin/perl

use strict;
use warnings;
use File::Spec;


if (scalar(@ARGV) != 2) {
    print "Usage: perl $0 <range.txt> <code.txt>\n";
    exit -1;
}

my @field;
my @fieldd;
my @start;
my @end;
my @numb;
my $start;
my $end;
my $numb;
my $fieldd;
my $field;
my @code;
my $code;


open(RAN, $ARGV[0]);
open(COD, $ARGV[1]);

while (<RAN>) {
    my @field=split(/\t/, $_);
    push(@eleR, $field[0]);
    push(@start, $field[1]);
    push(@end, $field[2]);
    
    while (<COD>) {
        my @fieldd=split(/\t/, $_);
        push(@eleC, $fieldd[0]);
        push(@numb, $fieldd[1]);
        push(@code, $fieldd[2]);


    foreach $eleC (@eleC) {
        if (grep (/$eleC/, @eleR)) { 
        foreach $numb (@numb) { if ((@start <= $numb) && ($numb <= @en
+d))
        {print "$code\n"}}}}}

close(RAN);
close(COD);

NB: I know this was covered times -> I tried to assemble something by myself and this is the best I could. There is no result & it's incorrect, but I might be going into the right direction. I can't install any new CPAN or something (do not have root permission). There is definitely too much junk in my code, but I am afraid to delete something (it might be necessary).

I hope that someone could help me with this. I've started Perl from scratch on Monday & it's almost Friday. Can't stand such "no result wasted week".

Looking forward
